16 Claims. (Cl. 88-24) This invention relates to mechanism for feedingand cutting oil a web of sheet material in photographic copying machinesand the like, and more particularly automatic machines such as thosewhich expose and process photographs automatically, one object being theprovision of a more practical machine of this nature.

Photographic copying machines of this description generally comprisemeans for holding a web or roll of photographically sensitized sheetmaterial in the focal plane, optical components for focusing an image onthe sheet material, means for feeding the sheet material into the focalplane for exposure, means for removing the exposed photographic materialfrom the focal plane, and means for developing and processing theexposed material.

Machines of this nature are generally used for copying documents. Sinceit is often desirable to reproduce both sides of a document suchmachines often utilize photographic materials sensitized on both sides.In this case, means are desirable for reversing the position of thesensitized material for exposure of the rear surface, and the provisionof such means is another object of this invention.

It is desirable that the operations of winding, exposing, reversing,developing, and processing can be carried out automatically withoutintervention of the operator. For this reason, suitable interlockingcontrol means are desirable to synchronize the various parts of themachine in order to carry out the steps automatically, and provision ofsuch a system is another object of this invention.

Copying machines of this nature generally are provided with spools ofsensitized paper and it is necessary that the sensitized material beprotected from light prior to exposure. Further, since such spools ofsensitized paper are large and bulky, it is desired that the loading ofthis material in the machine be facilitated as much as possible. Forsuch reasons, other objects include the provision of a light tight papermagazine and one which is also easily opened for convenient loading ofspools of paper.

It is often desirable to use machines of this nature for reproducingdocuments of varying sizes. For this reason, another object of thisinvent-ion is the provision of adjustable parts adapted to take paper ofvarying widths, and the provision of means for varying the length ofpaper exposed during each operation.

Cameras of this nature have performed numerous operations such aswinding and cutting of paper, and the mechanisms that do this have beengenerally complicated and required a plurality of motors. Therefore,another object of this invention is the provision of a simplifiedmechanism to perform these multiple functions, and the provision of atransmission capable of using one motor to perform both the winding andcutting functions.

Other objects include the provision of photographic copying machineswhich are more simple and practical in construction, more readilymanufactured, and more eliicient and convenient in operation than thoseheretofore in use.

This application is a continuation of application Serial No. 504,850,filed April 29, 1955, and now abandoned.

To these and other ends the invention resides in certain improvementsand combinations of parts, all as will be hereinafter more fullydescribed, the novel features being pointed out in the claims at the endof the specification.

A photographic copying camera embodying this invention is showngenerally in FIG. 1 as illustrative of the principles involved. Thecamera may be generally described as comprising a frame means forsupporting the operative parts, optical means for focusing an image, apaper magazine for storing and supplying paper, winding means forsupplying paper, cutting means for severing the exposed sheet, andprocessing means for developing the exposed photograph.

The supporting frame 50 comprises two vertically extending channelmembers 52 (FIG. 1) rigidly connected by a horizontal cross member 54, afront plate 56 (FIG. 2) and a rear plate 58. A pair of rearwardlyextending horizontal channel members 60 are rigidly fastened to thelower end of the channels 52 by means of gussets 62 and are providedwith leveling screws 64 for supporting and leveling the frame invertical position.

The optical components of the camera comprise a lens and mirror assemblymounted on the front plate 56 and connected thereto by a bellows. Thelens 66 is mounted on a lens board 68 which is supported in turn by abracket 70 slidably mounted on a horizontally extending track 72. Track72 is rigidly maintained in aligned position by a track supportingmember 74, fastened to channels 52. A bellows 76 connects lens board 68to an opening 78 (FIG. in plate 56 providing a movable, light-tightconnection therebetween.

A mirror 80 is mounted on lens board 68 at an angle of for reflectinginto the lens the image of the object to be photographed, as is wellknown in the art.

The object to be photographed is supported in a horizontal plane underthe lens system by a vertically movable horizontal platform 82 slidablymounted on the lower rear plate 58. Platform 82 is supported by a pairof parallel, forwardly extending arms 84 which are vertically movablebeneath the reversing mirror 80. This movement, in combination with thehorizontal movement of the lens 66, varies the magnification of theimage on the photographic paper, as is well known in the art.

The photographic paper is stored and exposed in an enclosure 86, whichis hinged to the frame by means of hinges 88 (FIG. 5). Enclosure 86comprises a base frame 92 (FIG. 3) having a large circular opening 94, atop frame 96, a front frame 98 (FIG. 5) and sheet metal panels 1116,which are attached to frames 92, 96, and 98 to form a light tightenclosure for the photographic paper, when the enclosure 86 is locked inposition against the frame 50.

The paper holding and exposing assembly 102 (FIGS. 3, 4 and 5) comprisesa paper magazine, a mask, a winding and cutting means, and associatedparts all mounted on a horizontal, circular turntable 104 rotatablymounted in enclosure 86. Turntable 104 is rotatably mounted in order topresent both the back and front surface of the double coatedphotographic paper to the lens, so that both sides may be successivelyexposed, as described below. The edge of turntable 104 is formed with aperipheral V shaped groove 106 (FIG. 3) which is engaged by threeequally spaced V shaped rollers 108, 110 and 112 (FIG. 5) which arerotatably mounted on short, vertical shafts 114, 116, and 118 on thebase frame 92, in such a manner that the turntable 104 is free to rotatein a horizontal plane. Roller 112 (FIG. 5) is mounted on an adjustablebracket 120 which is pivotally mounted on bolt 122 and has an adjustingscrew 124 whereby the roller may be moved inwardly into the groove 106for taking up any play that may occur in the turntable 104.

Four upwardly extending rods 126 (FIGS. 3, 4 and 5) are mounted adjacentthe edge of turntable 1114. Rods 1 26 rigidly support a horizontalplatform 128, having a transverse slot 130 and a vertical panel 132 uponwhich is mounted a reversible motor 134 having a speed re ducerconnected thereto (FIG. 4), whose function will hereinafter bedisclosed.

The paper magazine 136 (FIG. 4) comprises a spool holder pivotallymounted on platform 128. The spool holder comprises a holder frame 140having a transverse track 142 upon which is mounted two spool holdertrunnions 144 for holding the paper spool 146. Trunnions 144 arelateral-1y adjustable on track 142, and may be spaced to hold rolls ofpaper of any desired width, and may be clamped in adjusted position bymeans of wing nuts 148 (FIG. 3). A cover 150 is slidably mounted on theplatform 128 to shield the photographic paper from light when theenclosure 86 is opened for adjustment. A pair of paper guiding andtensioning rollers 152 and 154 are mounted, one above the other, on avertically ex tending bracket 156 which is mounted adjacent the frontedge of frame 140. Lower roller 154 is yieldably urged in itsforwardmost position by a spring 158 in order to engage a third roller160 mounted in a bracket 162 on the vertical panel 132 in linetherewith. Rollers 152, 154 and 160 serve to guide the paper from theroll to the mask, as hereinafter described.

Spools of paper are inserted in magazine 136 as follows: Enclosure 86 isopened and turntable 164 is manually rotated to bring magazine 136 to aposition adjacent to the opening in enclosure 86 as shown in FIG. 4.Cover 1511 may then be easily removed through the frame 98 to expose thespool holding parts. The spool holder frame 140 is then pivoted upwardlyand outwardly to the position shown in dotted lines in FIG. 4, so thattrunnions 144 are easily accessible. Frame 140 is retained in convenientposition for loading by a lug 164, which engages platform 128, as shownin the figure. The trunnions are set at the proper width to accommodatea spool of paper, and the spool is placed in position therebetween.

The leader on the photographic paper is unwound to a substantial lengthand the end threaded through slot 138' in the platform 128. The spoolholder frame is then revolved back to normal position, with the paperlying over roller 152 and between the tensioning rollers 154 and 160.The angle at which the paper passes through slot 138 into the exposurezone is maintained constant by these rollers, regardless of whether thespool is full or partly empty, thereby assuring the precise position ofthe paper in the focal plane in order to produce a sharp image.

A microswitch 166 (FIG. 4) is mounted on panel 132. An outwardlyextending arm 168 engages the paper leaving the roll, and will drop intothe slot customarily left on each side of a splice, as described in thepatent to Paul Landrock, Patent No. 2,109,373 issued February 22, 1938.Microswitch 166 is connected to a warning buzzer 170, as shown in FIG.21, to warn the operator of the imperfection in the paper.

The paper passes through a slot 130 to a mask 172 positioned in thefocal plane of the lens. A pair of flaps 174 are hingedly fastened tothe bottom of plaform 128 as shown in FIG. 4, to prevent light fromexposing the paper between the platform and the top of the mask.

The paper is held in flat position for exposure in the focal plane ofthe lens by mask 172. Mask 172 (FIGS. 3 and 20) comprises two metalsheets 176 having exposure openings 178 (FIG. 3) and separated by twostrips 188 to provide a slot 182 (FIG. 20) for holding the photographicpaper flat in the focal plane. The openings 178 are in alignment so thatthe images on opposite sides of the finished print are in registration.The size of openings 178 can be varied depending on the size of printdesired, and strips 180 can be placed at varying distance apart toaccommodate different widths of paper.

Mask 172 is supported in the exact center of the turntable 104 (FIG. 4)by brackets 182 mounted on horizontal bars 184 which are secured to theupright rods 126. Spring loaded locking devices 186 are provided forholding the mask in yielding contact with brackets 182 assuring properpositioning of the mask.

The paper is held tight in mask 172 by a pair of rollers 188 and 1%(FIGS. 2 and 5) which are mounted in an opening 192 (FIG. 13) inturntable 164 adjacent the bottom of the mask. Roller 188 is mounted inbearing members 194 (FIG. 5) on a pair of guide members 196, as shown inFIG. 2. Roller 190 is mounted on a pair of arms 198 which are, in turn,pivotally mounted in bearing members 194. Arms 198 are resiliently urgedin a counter-clockwise direction (FIG. 2) by a pair of springs 200,thereby pressing roller 190 tightly against roller 188, to assuregripping contact with the paper passing therebetween.

A pair of connecting gears 20 2 and 204 (FIG. 5) are mounted at one endof each of winding and pressure rollers 188 and 194 so that both of therollers rotate in synchronism to pull the paper therethrough when therollers are brought together.

In order to facilitate the threading of the paper between rollers 188and 191 a shaft 206 (FIG. 2) is pivotally mounted in bearing members 194and has a handle 208 (FIG. 5) at one end. Shaft 206 is adjacent to arms198 and has a flattened portion 210 which engages a finger 212 (FIG. 2)on the arms 198 in such a manner that when the handle 208 is moved toturn the shaft 206, arms 198 are turned to move the pressure roller 190away from the winding roller 188 against the urging of springs 200, sothat the paper can be threaded freely between the rollers. When thehandle is released, springs 200 return roller 190 to its initialposition engaging roller 188, to firmly grip and wind a sheet of paper.

Paper cutting means are mounted on the lower surface of turntable '4,directly under rollers 188 and 190 (FIGS. 2 and 6-). The paper cuttingmeans comprises a stationary knife member 214 and an opposed movingknife member 216 slidably mounted at an angle in stationary guidemembers 196 secured to the bottom of turntable 104 (FIGS. 2 and 6).Knife 216 is provided with a pair of inwardly extending pins 218 forconnection with the actuating mechanism, as described below. A guide bar220 is positioned parallel to and spaced from the stationary knife forholding the paper during the cutting operation and preventing thesevered edge from being moved out of alignment by the sliding knife 216on its return stroke.

The roller and knife mechanisms are driven by reversible electric motor134 (FIG. 4). Motor 134 drives chain 238 to drive a transmission unit222 (FIGS. 4 and 5 and 7-12). When the latter is driven in its normal orforwardly direction, it actuates rollers 188 and 190 through chain 260(FIG. 5 winding ofi paper until a synchronous motor timer (574 in FIG.21), which forms part of the electrical control circuit hereinafterdescribed, stops the motor and causes the same to reverse. Timer 574 iscalibrated to wind off a sheet of paper of the length required for oneprint. When motor 134 reverses, transmission unit 222 actuates the knifemechanism, as described below.

Transmission unit 222 (FIGS. 7 to 12, inclusive) comprises three axiallyaligned shafts 224, 226, and 228 mounted in bearing members 230 and 232which are secured to turntable 104 in parallel relation to the windingrollers. Shaft 224 is connected to shaft 228 by means of aunidirectional, single revolution clutch, shown generally at 234 (FIGS.7 and 8) and is integral with shaft 226. Shaft 224 is driven by asprocket 236 which is driven by motor 134 through chain 238.

Unidirectional clutch 24-2, shown in detail in FIG. 9, is mounted onshaft 224 adjacent sprocket 236. Clutch 242 comprises a drive member 244of square cross section mounted on shaft 224, a driven member or housing246 mounted on shaft 226, and a cage 248 (FIG. 8) mounted therebetween.Cage 248 carries a plurality of rollers 250 (FIG. 9) which are yieldablyforced in one direction by springs 252. A sprocket wheel 254 (FIG. 8) isrigidly mounted on the outer end of housing 246 and the entire assemblyis free to turn on shaft 226 in one direction and is held in lateralposition by collar 256 pinned to shaft 226.

When shaft 224 is turned in counterclockwise direction as viewed in FIG.9, rollers 250 are wedged between drive member 244 and housing 246, andturn the housing, along with sprocket wheel 254, in the same direction,as indicated by the arrow in FIG. 7. However, when shaft 224 is turnedin the opposite direction, rollers 250 will slip and permit shaft 224 toturn freely without affecting housing 246 or sprocket wheel 254, so thatthe latter remains stationary.

Sprocket wheel 254 drives a second sprocket wheel 258 on the windingroller 1'88 (FIGS. 4 and 5) through a sprocket chain 260, so that whenthe shaft 224 turns in one direction, the roller clutch will drive thewinding rollers to wind a sheet of paper. However, when the shaft 224turns in the opposite direction the winding rollers are not affected,and remain stationary.

The paper is wound by rollers 188 and 190 against the yieldingresistance of spring loaded rollers 154 and 160, as described above.This tension is desirable in that it serves to hold the paper fiat inthe focal plane of the lens and resists the natural tendency of thepaper to curl and buckle. However, it has been found that drivesembodying a plurality of sprocket chains and clutches tend to have acertain amount of lost motion or backlash which would allow rollers 188and 190 to turn slightly in a reverse direct-ion. This would relieve thetension on the paper, and result in the curling and buckling describedabove. In order to prevent this, a roller clutch 262 (FIGS. 5 and 19) ismounted on one side of one of the bearing members 194. Clutch 262comprises stationary housing 264 (FIG. 19) into which projects anextension 266 of the winding roller 188. A star wheel 268 is secured tothe extension 266 and engages rollers 270. The latter are yieldably heldin position by springs 272 in such a manner that when the winding rolleris turned to feed paper, star wheel 268 turns in the direction of thearrow in FIG. 19 and rollers 270 will slip on the inner face of thehousing 264. However, when the winding rollers stop, rollers 270 arewedged between housing 264 and the star wheel, and prevent any reversemotion or backlash of the winding rollers.

The cutting knife is actuated when motor 134 runs in reverse direction.Power is transmitted to shaft 224 by chain 238, and thence to shaft 228through unidirectional single revolution clutch 234, mentioned above.Clutch 234 comprises a toothed wheel 274 (FIGS. 7, 8 and 10) fixed toshaft 224, and an arm 282 pinned to shaft 228. A dog 278 (FIG. 10) isfixed on a pin 28*4 rotatable in the outer end of arm 282 in position toengage the teeth of wheel 274. The opposite end of pin 284 carries anarm 286 (FIG. 12) fixed thereon and having a spring stud 290 whichcarries a spring 292 which extends to a spring stud 294 on an extension296 of arm 282. The force exerted by spring 292 resiliently urges arm286 downwardly, tending to rotate pin 284 in a clockwise direction asviewed in 'FIG. 12, thereby urging dog 278 inwardly, towards toothedwheel 274.

This movement of arm 286, pin 284 and dog 278 is prevented by ahalf-moon shaped pawl 280 mounted on and extending laterally from arm286. Pawl 280 engages a laterally extending arcu-ate shaped cam 298(FIGS. 7 and 10). Cam 298 is mounted on a pin 300 rotating in alaterally extending stationary arm 302 (FIG. 7) which forms an integralpart of bearing member 232. A lever 304 is fixed to the opposite end ofpin 300. The outer end of lever 3,04 is pivotally attached to a link 306which is yieldalbly urged inwardly by a spring 308 attached to a springstud 3 10 on bearing member 232. The opposite end of link 306 isconnected to the armature of a solenoid 312 (FIG. 10).

Referring to FIG. 10, it should be noted that half moon shaped pawl 280normally rests on earn 298 thereby holding dog 278 in inoperativeposit-ion away from toothed wheel 274, so that the wheel 274 is free toturn in either direction. However, when solenoid 312 is actuated, lever304 is turned counterclockwise around pin 300 (FIG. 7), moving cam 298away from pawl 280, permitting the latter to drop off the lower edgethereof. This allows the arm 286 to move under the influence of spring292, turning pin 284 to bring dog 278 into engagement with toothed wheel274.

When dog 278 engages wheel 274 as described above, the dog, arm 282 andshaft 228 rotate as a unit, carrying arm 286 and dog 278 around withthem. As shaft 228 rotates, it turns cam 31-4 mounted on the endthereof. A microswitch 316 is mounted adjacent earn 314 having itsoperative part in engagement therewith, so that the rotation of the camactuates the switch. Oarn 314 is so cut that it actuates the microswitch316 after revolving a short distance. Microswitch 3'16 breaks thecircuit to solenoid 312, deenergizing the same, allowing cam 298 toreturn to its initial position under the urging of spring 363.

When arm 282 and its associated parts have made one complete revolution,pawl 280 strikes cam 298 (which has returned to its original position),thereby disengaging dog 278 front wheel 274, breaking the connectionbetween this wheel and arm 232. Arm 232 and shaft 228 then come to astop. Thus, arm 2S2, shaft 228 and cam 3114 make a single, completerevolution every time solenoid 312 is energized. A r-m 282 is finallyarrested by engagement of its lug 283 with arm 286.

A second microswitch 404 is mounted adjacent a second cam surface of cam314 (FIG. 7). Switch 404 is part of the electrical control circuit,hereinafter described, and serves to break the circuit to motor 134after shaft 228 makes its single revolution, as described above.

An outwardly extending eccentric pin 318 is rigidly mounted on the freeface of cam 314 (FIGS. 5, 7 and 10). Pin 3118 is connected through link329 ('FIG. to a lever 322 on the knife operating shaft 324 (FIGS. 2 and5). When the one revolution clutch 234 is actuated to make a singlerevolution, pin 318 moves link 323 and lever 32 2 forwardly andbackwardly, rocking shaft 324. This rocking action of shaft 324 movesthe knife 216 inwardly relative to the stationary knife 214, to cut offa sheet of paper, and returns it to its original position. A spring 326,connected to the pin 318 and fastened to the turntable 104, resilientlyopposed the rotation of cam 314, shaft 228 and arm 282, therebyresiliently forcing the halfmoon shaped pawl 280 downwardly against thecam 298 preventing rota-tion of arm 28 2 when toothed wheel 2'74 isturned in the opposite direction.

The operation of the winding and cutting mechanism just described takesplace when the reversible motor 134 is actuated by the electric controlcircuit in such a manner that it makes a predetermined number ofrevolutions in a counter-clockwise direction, as viewed in FIG. 4,reverses, and makes a predetermined number of revolutions in theopposite direction. When running in a counterclockwise direction themotor drives the sprocket 236 through chain 238, causing clutch 242 toengage and drive sprocket 254. The latter drives sprocket 258 throughchain 260, causing rollers 188 and 198 to operate to wind off a sheet ofpaper of predetermined length. After the requisite amount of paper hasbeen wound off, motor 134 is reversed and solenoid 312 is momentarily energized by the electric control circuit. Shaft 224 is now rotating inthe opposite direction, so clutch 242 disengages, breaking the powertrain to the winding rollers, so these remain stationary. However, sincesolenoid 312 has tripped the single revolution clutch, the latterengages and causes cam 314 to make one revolution, actuating the knifemechanism to cut off the sheet of paper extending below the rollers.

As the sheet passes downwardly from the enclosure 86, it passes througha slot 328 (FIG. 2) and a light guard 330 on the top of the processingunit 332, and then through a guiding chute 334 into the processing tanksfor developing and processing, in the manner described in the copendingapplication of Ernest P. Taubes, Serial No. 408,119, filed February 4,1954. Processing unit 323 delivers the processing print to a drier 335.Drier 335 may be of any of the known types of belt or drum driers, whichoperate continuously, and which deliver the dried print in condition forimmediate use.

Turntable 104 is rotated by a second reversible motor 336 (FIGS. 2 and5). Motor 336 is mounted on a frame 338 which is pivotally mounted in abracket 341) secured to the front plate 56 of the stand 56. Frame 338carries bracket 342 which rotatably supports an upwardly ex tendingshaft 344. A V-shaped friction drive wheel 346 is rigidly mounted at thetop of shaft 344 and engages 1n the V-groove 106 in the periphery ofturntable 184. Bracket 338 is provided with an adjusting screw 348 whichextends through the bracket 338 and front plate 56 and threadedlyengages a sleeve 350. A spring 352 is provided to yieldably urge bracket333 towards turntable 104, assuring tight, frictional contact of wheel346 therewith. A nut 354 adjacent the inner end of screw 348 limits theinward movement of bracket 338 so that when the enclosure 86 is opened,the motor and friction wheel move only slightly out of position,retaining these parts in proper position to engage turntable 164 whenenclosure 86 is closed.

In order to limit the movement of turntable 104 a lug 356 (FIG. 5) ispositioned thereon in position to contact an adjusting screw 358 in abracket 360 mounted on the base frame 92. A second adjustng screw 362 ismounted in a bracket 364 mounted on frame 92 in a position diametricallyopposite to that of bracket 360. Brackets 368 and 364 are positioned tostop the rotation of turntable 104 when mask 172 is in position to holdthe photographic paper in the focal plane of the lens. Adjusting screws358 and 362 are provided to permit accurate adjustment of the twopositions of turntable 104.

A switch assembly 366 (FIGS. 13-16) is mounted on a bracket 368 adjacentto turntable 104. Switch assembly 366 comprises a single-throw,double-pole mercury switch 370 mounted on a shaft 372 pivotally mountedin bracket 368. A long arm 374 and a short arm 376 are mounted atdivergent angles on the inward end of shaft 372, as shown in FIG. 14. Apair of spaced, inwardly extendng pns 378 and 380 are mounted on bracket368 to limit the movement of arms 374 and 376 and the rotation of shaft372. Also mounted on shaft 372' is an upwardly extending arm 382 (FIG.15) connected to a second arm 384 on bracket 368 by a tension spring 386which imparts an over-center toggle action to switch 370, so that whenshaft 372 is rotated past dead center in either direction, spring "386will cause the switch to move quickly to the limit of travel in thatdirection, as determined by pins 378 and 380.

A pair of outwardly extending lugs 390 and 392 are clamped todiametrically opposite rods 126, as shown in FIGS. 4 and 13. As shown inFIG. 4, lug 390 is disposed slightly higher than lug 39-2 and, as shownin FIG. 13, lug 391) is shorter than lug 392. These lugs are positionedso that they will contact the long and short arms 374 and 376respectively when they move past switch assembly 366, moving these torotate shaft 372' to reverse the position of mercury switch 370.

When motor 336 is started at the proper time by the electrical controlcircuit, as hereinafter described, it rotates turntable 104 by means offriction wheel 346, as described above. Assuming that the turntablerotates in a clockwise direction as viewed in FIG. 13, lug 390' willmove past arms 376 and 374. However, lug 390 will not contact either ofthese arms; it misses arm 376 because the latter is in its highestposition as shown in FIG. 14, and the lug passes therebeneath, and itmisses arm 374 because this arm is placed further from turntable 104,and lug 390 is not long enough to reach it. Thus, the position ofmercury switch 370 is not affected by lug 390. However, further rotationof turntable 104 moves lug 392 around to engage switch assembly 366.Since lug 392 is lower than lug 390, it also misses arm 376, but beinglonger, it engages arm 374, moving it to the right as viewed in FIG. 14,and rotating shaft 372- in a counter-clockwise direction. This rotationof shaft 372 moves arm 382 upwardly against the tension of spring 386until it passes the vertical position, when the tension of the springquickly completes the rotation of shaft. This movement reverses theposition of mercury switch 370', which stops motor 336, allowingturntable 184 to coast until it is stopped by the contact of lug 356against screw 362.

A pair of micro-switches 396 and 398 are mounted adjacent the top ofswitch 366 in line with cams 400 and 482 (FIGS. 4 and 5) mounted on theupright rods 126 on opposite sides of the turntable 104, injuxtaposition to lugs 390 and 392. Immediately following the stopping ofthe motor and as the turntable coasts to a stop against adjusting screw358, cam 45 engages micro-switch 396, depressing it as shown in FIG. 5,which actuates the electric control circuit to reverse the motor 336.

After the exposure has been made on the opposite side of the paper,motor 336, which has been reversed as described above, is started by thecontrol circuit and the turntable 104 is revolved in the oppositedirection. As it approaches the end of its travel, lug 392 actuates thearm 374 again reversing the position of mercury switch 370 and stoppingmotor 134. As turntable 104 coasts to a stop against adjusting screw362, earn 402 operates microswitch 398, which actuates the controlcircuit to start the motor 134 on the paper exposing assembly 102 towind and cut off a sheet of paper as described above.

During the cutting operation, cam 314 (FIGS. 5, 7 and 11) makes a singlerevolution, as described above. At the end of this revolution, cam 314actuates a microswitch 404 (FIGS. and 7) thereby stopping the machine.The camera is now in position to repeat its cycle when actuated by theoperator.

The electrical control circuit, shown in FIG. 21, comprises a series ofswitches, relays, and other components, connected to a source of poweras shown in the diagram. Its construction and the functions of thecomponent parts are best described by describing a cycle of operation asfollows: Main switches 500 and 501 are closed, supplying power to mainlines 502 and 503. Switches 504 and 505 are closed to start theprocessor and drier. These mechanisms operate continuously during theperiod when the camera is in use, to process :and dry the photographicprints as they are exposed by the camera.

The camera is now ready for the first exposure. The ready pilot light507 will be on, indicating this to the operator. When the operatordepresses exposure button 509 microswitch 510 is actuated closing thecircuit from wire 503 to wire 512 and energizing relay 513. Even thoughthe push button contact is only momentary, relay 513 maintains thecircuit from Wire 503 to wire 514 back to wire 512 so that timer 515,shutter solenoid 516, shutter pilot light 517 and relay 513 areenergized until preselected exposure time has expired.

When the shutter solenoid 516 closes, it mechanically actuatesmicroswitch 518 so that current is carried from wire 519 to wire 521.Wire 519 receives its current through a multiple exposure switch 522from wire 503, and therefore line 503 is connected through wire 519 towire 521, and through wire 521 to the closed contacts of a relay 524through wire 525 to relay 526 to energize the latter.

When relay 526 is energized, it closes contacts on both sides of itsarmature. On one side it closes contacts between wires 528 and 530, andon the other side between wires 532 and 533. Both wires 528 and 530 areconnected to a double-pole, double-throw switch 535. This switch isprovided to allow operation of the camera to expose photographic papersensitized on one or both sides. When it is desired to expose both sidesof the paper, the turntable must be rotated between successiveexposures. This will hereinafter be referred to as Duplex operation.Where the paper is sensitized on one side only, it is not necessary torevolve turntable 35 between successive exposures. This will behereinafter referred to as Simplex" operation. Simplex-Duplex switch 535may be set to bypass the table turning function of the control circuit.

Assuming that switch 535 is set for Duplex operation, wire 530 connectsthrough switch 535, to wire 537 which in turn carries current frommicroswitch 398 on turntable 104 and which is connected to line 503. Thecurrent flows from line 503 through microswitch 398, through wire 537,through switch 535 and to wire 530, thence through the relay 526 to wire528, through the switch 535 again, and through wire 525 to the relaycoil of relay 526. This current will maintain relay 526 in energizedcondition, even though shutter solenoid 516 is de-energized and 10breaks the connection between wires 519 and 521. Once timer 515 hascompleted its pre-set cycle, it will break the connection between wires514 and 512, thereby de-energizing relay 513 and disconnecting thecurrent from shutter pilot light 517.

Once shutter solenoid 516 is de-energized, it releases microswitch 518which re-establishes connections between wires 519 and 532. This permitscurrent to flow through wire 519 into wire 532, through relay 526 towire 533, and thence to the mercury switch 370 described above. Thecurrent passing through switch 370 travels along wire 539, through relay540 to turntable motor 336. This current actuates motor 336 to rotateturntable 104 as described above. As soon as turntable 104 rotates cam400 mechanically releases microswitch 396 so that the connection fromswitch 370 through wire 542 is switched from wire 544 to wire 546. Atthe end of the rotation of tumtable 104, cam 402 and lug 392 actuatemicroswitch 398 and mercury switch 370, respectively, as explainedabove. Microswitch 3-98 switches the connection of line 503 from line537 to line 548. The disconnection of line 537 from the source ofcurrent from line 503, de-energizes relay 526. The relay then breaks theconnection between wires 532 and 533, cutting off the current actuatingturntable motor 336.

The actuation of mercury switch 370 breaks the connection between wires533 and 539, and, at the same time, establishes a connection betwenwires 539 and 542. Turntable 104 is now in reversed position, presentingthe back of the photographic paper to the lens, and the followingconnections have been established: Microswitch 398 has connected wires503 and 548, energizing relay 540 and lighting pilot light 551 on thecontrol panel, which indicates that the back surface of the paper isready for exposure. Mercury switch 370 has established a connectionbetween wires 539 and 532. Microswitch 396 has connected wires 542 and546. The energizing of relay 524 has established contact betwen wires521 and 552, which is connected to the center terminal of relay 554. Theenergizing of relay 540 has reversed the field connections of turntablemotor 336 so that when the latter is next energized, it returns theturntable 104 to its initial position.

The second exposure is made by depressing exposure button 509, startingthe following cycle. The sequence of operations is the same as describedabove, wherein the momentary contact of microswitch 510 connects wires503 and 512 thus energizing relay 513. Shutter solenoid 516 and shutterpilot light 517 are energized, as before. Even when the button 509 isreleased, current will be maintained through wires 503 and 514 and relay513 until timer 515 has completed its pre-set cycle. When shuttersolenoid 516 is energized, it will trip microswitch S18 connecting wires519 and 521. This energizes relay 554 through the connection alreadyestablished in relay 524. Relay 554 connects wires 552 and 556 on oneside to hold relay 554 closed. Wire 556 is connected to power line 503through microswitch 404 which is located on turntable 104, describedabove in connection with the winding mechanism.

When shutter solenoid 516 is energized, it moves micro switch 518 toconnect wires 519 and 532 sending current through wire 532 throughrelays 526 and 554 to wire 542. The latter is connected to wire 539through mercury switch 370 and this energizes turntable motor 336 torotate turntable 104 to its normal starting position. This alsoenergizes relay 562 through wire 542 and wire 546 on microswitch 396.

As soon as turntable 104 beings to rotate, cam 402 disengagesmicroswitch 398 breaking the connection between wires 503 and 548 andre-establishing contact between wires 503 and 537. Relay 562 establishesa connection between wires 546 and 548, thereby maintaining relays 524and 540 in energized condition, despite the fact that 1 1 connectionsbetween lines 503 and 5 on microswitch 398 have been broken.

When the turntable completes its rotation, it returns mercury switch 370back to its original position, connecting wires 539 and 533 and breakingthe connection between 539 and 542, thus stopping the turntable motor.It also actuates microswitch 396, stopping the flow of current betweenline 542 and line 546 and establishing contact between wires 542 and544. This allows current to flow, through wire 544 to relay 564, keepingit energized, and at the same time energizes the counter solenoid 567 toadvance it one digit. The disconnecting of wire 546 de-energizes relay562 and this in turn, disconnects the current from relay 5224, relay 540and the pilot light 551.

When relay 564 is energized as described above, it closes contactsbetween power line 5&3 and wire 566 sending power to fixed intervaltimer 568 at the same time disconnecting power line 593 and 570 whichcarried current to pilot light 567. This extinguishes pilot light 5437,indicating that the paper in exposure zone is exposed.

A delay timer 563 is provided in the winder circuit to prevent thelatter from operating to send a print to processor 332 before thepreviously exposed print has cleared entrance chute 334. If delay timer568 has completed its cycle from the previous exposure and is in closedposition, the current is able to flow from wire 566 to wire 572 into apaper winding timer 574, preferably a synchronous motor as shown in FIG.21, and thereby actuate that timer so that its timing cycle will begin.As soon as this timer receives current, it also carries the currentthrough the wire 576 back to the paper winding and shearing motor 134,to start the same in order to wind paper into the processor. Timer 574is preferably an adjustable seconds timer which permits the windingmechanism to run for a predetermined number of seconds, and thereforewind a predetermined length of paper. This timer can be set to variousnumbers of seconds and therefore permits various lengths of the paper tobe wound off.

Since winding rollers 188 and 194 revolve at a constant speed asdetermined by speed of motor 134 and its associated driving means, thelength of paper to be wound off may be controlled by varying the settingof timer 574. In a machine of this type wherein documents of varioussizes are to be photographed at various magnifications, it is essentialto be able to wind and cut off sheets of various lengths. Timer 574provides automatic means for accomplishing this.

When the preset time for which timer 574 has been set has elapsed, thelatter breaks the connection between wire 572 and wire 576 and, at thesame time, establishes contact between wires 572 and 578. This energizesrelay 580, connecting power wire 5%3 and wire 582 thereby energizingrelay 584. Relay 584 reverses the connection of winding field coils ofthe motor 134 so that it reverses its rotation, and, at the same time,sends current to knife actuating solenoid 312 on the turntable 1041,releasing the pawl to engage the single revolution clutch. This actuatesthe knife mechanism, as described above, cutting off the photographicpaper and allowing it to drop into the processor.

During the revolution of the single revolution clutch, cam 314 firstactuates microswitch 4G4 breaking the connection between power line 503and 556, and connecting wires 503 and 578 thereby stopping the currentwhich was flowing from power line 503 through wire 556, through thecontacts of relay 554 and into the coil thereof keeping it energized.This de-energizes relay 554 and at the same time allowing current toflow directly through Wire 578 to the coil of relay 580. This maintainsrelay 58d and 584 in energizsed condition until the single revolution ofthe cut off mechanism has been completed, as described below.

When relay 554 is de-energized, it breaks the connections between Wires586 and 542 and between wires 542 and 544 in microswitch 396,de-energizing relay 564 and counter solenoid 566. Secondly, the cam 314breaks the connection between wires 502 and 588 on microswitch 590, andknife actuating solenoid 312, de-energizing the same, allowing the pawlof the single revolution clutch to fall into place as described above.When the revolution of the clutch has been completed, microswitch 404,is returned to its normal position, thereby breaking the connectionbetween wires 5G3 and 578, and re-establishing the connections betweenwires 503 and 556. This disconnecting of wire 578 de-energizes relay 580which in turn de-energizes relay 584 which stops the paper winding motor134. This completes the cycle of the camera, and every relay isde-energized and every switch is returned to its normal position.

it will thus be seen that the invention accomplishes its objects andwhile it has been hereindisclosed by reference to the details of apreferred embodiment, it is to be understood that such disclosure isintended in an illustrative, rather than a limiting sense, as it iscontemplated that various modifications in the construction andarrangement of the parts will readily occur to those skilled in the art,within the spirit of the invention and the scope of the appended claims.
